My baby is 17 months old, since 3 days , some black deposit appears on tongue, we tried to clean but it’s not going , please suggest what to do

A. A black deposit on your 17-month-old baby's tongue that isn't going away with cleaning could be due to several reasons, including a fungal infection (like oral thrush), a reaction to certain foods or medications, or poor oral hygiene. Here are some steps you can take: 1. **Oral Hygiene**: Gently clean your baby's tongue and gums with a soft, damp cloth or a baby toothbrush. Ensure you're doing this at least twice a day. 2. **Hydration**: Ensure your baby is drinking enough water throughout the day, as dehydration can sometimes cause changes in the tongue's appearance. 3. **Diet**: Check if there have been any changes in your baby's diet that could be causing the discoloration. Some foods or drinks can stain the tongue. 4. **Consult a Pediatrician**: If the black deposit persists or if your baby shows any other symptoms (like discomfort, bad breath, or difficulty eating), it's best to consult a pediatrician. They can examine your baby's tongue and provide a proper diagnosis and treatment plan. Oral issues in toddlers should be addressed promptly to ensure they don't affect your baby's health or eating habits.
